Snap To Road

Topic: Snap To Road

Hi GT

Would you please check possibility of add Snap To Road function? The idea is to have possibility in units (or user) setting to activate this function and tell Wialon to snap points to road. If there are some units which goes off-road or users who doesn't like it, they can deactivate it. The best is to add Snap To Road function to Gurtam Map as Google seems hard to use in some regions. They may be other alternatives for google like OSM that provide such API.

Re: Snap To Road

Hello, Hamed

How often do your clients face with the problem of mismatch a road and a track?
Do you think maps inaccuracy or devices cause the issue?
You mentioned that some clients don't like it. Maybe you can add some business cases when this feature can be useful. "Snap to road" feature will increase the time of building a track. In the case of using external sources, it will cause additional money expenses. That's why for such improvement we should have business reasons.

It's devices issue for sure

 Maybe you can add some business cases when this feature can be useful.

While you track vehicles and set some geofences as check points (like when you track buses and check points are stations) devices inaccuracy cause considering some check points missed while vehicle touched them. You may say draw geofences bigger, but proble is that sometimes vehicles goes inside 2-way streets and only on one side of street we have check points or stations. in these cases you have to draw geofences as small as you can and use high accuracy devices, snap to roads will help in this case. Another case is when you draw a linear geofence to control vehicles path, devices inaccuracy will cause mistakes in reports and reports says vehicles went out of geofence while it has never happened.

"Snap to road" feature will increase the time of building a track

I'm not sure if Gurtam maps has snap to road function or not, but I have to say, what we asked is not about Tracks only, we asked for a function in Wialon that if user applied it, then Wialon save more data in it's DB about units. Which data? It should check each point that device sends to Wialon and do correction on each points and save both point (the point is received from device and corrected point with snapp to road). Then, can use each sort of data (received or corrected) in whole system (reports, Notifications, Tracks). As I understand Google charge customers per each query, a way to decrease costs is to do these corrections each 6 hours or one time per day.

Re: Snap To Road

hhamedk, your idea is clear. As you see this request is not supported actively by our community.
Until we have no clear understanding that this feature is significant for users and their business, this idea will be kept in our backlog.
